An innovative project led by Houston-founded re:3D Inc. is one of six to move forward to the next phase of the National Science Foundation's Convergence Accelerator that aims to drive solutions with societal and economic impact.

The sustainable 3D printer company will receive up to $5 million over three years as it advances on to Phase 2 of the program for its ReCreateIt project, according to a statement from the NSF. Co-funded by Australia's national science agency, the Commonwealth Scientific and Industrial Research Organisation, or CSIRO, ReCreateIt enables low-income homeowners to design sustainable home goods using recycled plastic waste through 3D-printing at its net-zero manufacturing lab.

The project is in partnership with Austin Habitat for Humanity ReStores and researchers from the University of Wollongong and Western Sydney University. CSIRO is funding the Australian researchers.

In Phase II the teams will receive training on product development, intellectual property, financial resources, sustainability planning and communications and outreach. The goal of the accelerator is to promote a "circular economy," in which resources are reused, repaired, recycled or refurbished for as long as possible.

"Progress toward a circular economy is vital for our planet's health, but it is a complex challenge to tackle," Douglas Maughan, head of the NSF Convergence Accelerator program, said in the statement. "The NSF Convergence Accelerator program is bringing together a wide range of expertise to develop critical, game-changing solutions to transition toward a regenerative growth model that reduces pressure on natural resources, creates sustainable growth and jobs, drastically reduces waste and ultimately has a positive impact on our environment and society. Phase 2 teams are expected to have strong partnerships to ensure their solutions are sustained beyond NSF support."

Other teams that are moving forward in the accelerator include:

FUTUR-IC: A global microchip sustainability alliance led by MIT
PFACTS: Led by IBM's Almaden Research Center and aiming to replace, redesign and remediate fluorine-containing per- and polyfluoroalkyl substances (PFAS)
SOLAR: A team led by Battelle Memorial Institute using photovoltaic circularity to develop the technology needed to achieve sustainable solar recycling
SpheriCity: A cross-sector tool that examines how plastics, organics and construction and demolition materials flow through local communities developed by the University of Georgia Research Foundation Inc.
Topological Electric: Another MIT-led team, this group aims to develop electronic and energy-harvesting device prototypes based on topological materials.

Re:3d and 15 other teams were first named to the Convergence Accelerator in 2022 with a total investment of $11.5 million. At the end of Phase 1, the teams participated in a formal Phase 2 proposal and pitch, according to the NSF. The Convergence Accelerator was launched in 2019 as part of the NSF's Directorate for Technology, Innovation and Partnerships.

This is the latest project from re:3D to land national attention and funding. Last year the company was one of 12 to receive up to $850,000 from NASA's SBIR Ignite pilot for its project that aimed to develop a recycling system that uses a 3D printer to turn thermoplastic waste generated in orbit into functional and useful objects, according to the project's proposal.

In 2022, it was also among the winners of an inaugural seed fund expo from the U.S. Small Business Administration. It also earned the prestigious Tibbetts Award from the SBA in 2021. The award honors small businesses that are at the forefront of technology.

Re:3D Inc. was founded in 2013 by NASA contractors Samantha Snabes and Matthew Fiedler and is based in Clear Lake. It's known for its GigaBot 3D printer, which uses recycled materials to create larger devices. The company announced its new Austin headquarters earlier this year.

TotalEnergies expands solar joint venture with $1.2B portfolio in Texas, Ohio

solar expansion

TotalEnergies, a French company whose U.S. headquarters is in Houston, announced this month that it is expanding its renewable energy joint venture with New York-based investment firm KKR by adding 700 megawatts of utility-scale solar projects.

The deal will add three utility-scale solar assets in Texas and Ohio, which are expected to reach commercial operation by Q1 2027, according to a news release from the company. The portfolio is valued at $1.2 billion.

The 50/50 joint venture between TotalEnergies and KKR currently holds 1.4 gigawatts of renewable energy and will grow to 2.1 gigawatts.

The new deal is expected to close this year. Once completed, TotalEnergies will operate the assets. The electricity generated from the solar projects will be sold to third parties, the company reports.

The companies originally formed the joint venture about a year ago when TotalEnergies sold KKR a 50 percent stake in a North American solar portfolio valued at $1.25 billion. The deal originally included six utility-scale solar assets, primarily located in the U.S.

“TotalEnergies is a renewable energy industry leader globally, and we are thrilled to establish this joint venture with the TotalEnergies team to support their renewables business," Cecilio Velasco, managing director KKR, said in a release last year. “We have long been investors in renewables through our infrastructure platform, having committed more than $23 billion to date in energy transition investments. TotalEnergies’ North American solar portfolio is a great fit for us, representing high-quality renewable energy assets with long term contracts.”

TotalEnergies reports that by June 2026 it held more than 37 gigawatts of gross renewable power generation capacity. It aims to achieve over 100 terawatt-hours of net electricity production by 2030.

The company signed a major power purchase agreement with Google earlier this year. Through the deal, TotalEnergies will supply the tech giant with 1 gigawatt of solar power for its data centers in Texas over a 15-year span.

However, the company also recently redirected nearly $1 billion in capital away from wind energy projects and "decided to renounce offshore wind development in the United States." Read more here.

Houston researchers develop compact carbon capture tech for data centers

AI emissions

Two scientists from the University of Houston have been experimenting with new carbon capture systems that fit inside a standard shipping container, which have the potential to make eliminating carbon output from industrial sites much easier.

The capture of industrial carbon is an important complement to the fight against climate change, as well as winning tax credits for businesses that use carbon capture technology.

The problem is that such systems are often measured in acres, making them expensive to build and extremely power-hungry to actually use. UH Engineering Professor Mim Rahimi and former UH Ph.D. student Ahmad Hassan (now a postdoctoral associate at Harvard) have managed to fit their new system, the Small Modular Electrochemical Container (SMECs), inside a standard 40-foot shipping crate, making them compact and modular enough to be installed almost anywhere for operations of all sizes. Their research was recently published in the journal Environmental Science & Technology.

“With a conventional system, you’re building a 130-foot-tall structure designed for a specific power plant. With our technology, we can adjust the capacity by simply turning containers on or off,” Rahimi said in a news release. “That flexibility is particularly important for data centers, where electricity can come from a combination of natural gas and renewable sources.”

Rahimi and Hassan used simulated gas models to show that under optimal conditions, the SMEC used electrochemically mediated amine regeneration (EMAR) cells developed in Rahimi’s lab to capture 90 percent of carbon under optimal conditions through 300 cycles over 50 hours.

Encouraged, the team then modeled a 360-megawatt natural gas power plant associated with OpenAI’s Stargate AI data center project in Abilene, Texas. In addition to the savings on infrastructure costs, 20 of the researchers’ shipping container systems were able to capture 98 percent of carbon from Stargate’s 875-acre campus based on the model.

The looming energy costs and subsequent carbon emissions from data centers are a real concern. Estimates from the U.S. Department of Energy hypothesize that 12 percent of America’s energy needs could be gobbled up by the centers as soon as 2028. That is a massive new source of carbon. The flexibility of the SMEC means they can be deployed wherever the centers spring up.

“We’re taking a technology that traditionally requires enormous infrastructure and finding a way to fit it inside a shipping container,” Rahimi added in the release. “That opens up entirely new possibilities for how and where carbon capture systems can be used.”

In the future, the researchers say they plan to look at ways to adapt the technology to capture carbon dioxide directly from the atmosphere.

Hertha Metals breaks ground on $100M high-purity iron factory in Conroe

coming soon

Shortly after announcing a $133.65 Series A funding round, Conroe-based Hertha Metals broke ground Oct. 8 on a $100 million factory that will produce steel-grade and magnet-grade high-purity iron.

Hertha’s Chalyx plant, located in Conroe, will manufacture a total of about 10,000 metric tons per year of magnet-grade and steel-grade high-purity iron. The factory will use Hertha’s single-step process to generate high-purity iron for rare-earth-magnet and steel manufacturers in the U.S.

Hertha says Chalyx will be the first U.S. commercial plant for production of magnet-grade high-purity iron.

Chalyx is being built next to Hertha’s headquarters and its Pi100 pilot plant, which will remain in operation. Chalyx and Pi100 will form the first modern-day iron and steel “innovation complex” in the U.S., the company says.

“I founded Hertha Metals because I believed we could significantly improve how the world makes iron and steel from ore, and that an industry so fundamental to our future still had enormous room for invention,” Laureen Meroueh, founder and CEO of Hertha, said in a press release.

The 4-year-old startup says the Chalyx complex will lay the foundation for its first 500,000-ton-per-year steel mill.

Chalyx’s first priority is making high-purity iron for U.S. manufacturers of rare-earth magnets, Hertha says. These magnets are critical components for electric vehicles, data centers, wind turbines and defense systems.

China produces an estimated 94 percent of high-purity iron for rare-earth magnets, according to Hertha.

Aside from iron for rare-earth magnets, Chalyx will make iron and steel for pilot projects in the steel industry.

The plant is expected to come online in late 2027, with production of magnet-grade high-purity iron starting in early 2028.

Today, Hertha employs 32 people, the company says. Once it’s fully operating, the Chalyx plant will employ about 50 people.

Just ahead of the groundbreaking, Hertha announced the $133.65 million Series A round, co-led by Khosla Ventures and Doerr Capital. The round included a $65 million equity investment from the Pentagon.

“Iron and steel have shaped human progress for thousands of years. And I believe there is still an enormous amount left to invent,” Meroueh said at the groundbreaking ceremony.
